    69088 is rated 2.5 out of 5 by 2.
    Rated 4 out of 5 by from Supercharger project on 1984 k-10 I was looking for an 1 3/4 inch tube header. These headers do look nice but I'm not sure the design is ideal. I had to clearance a few of the bolts just to get a box end wrench or socket on them. The design of the header tubes makes it difficult to bolt up the headers. They also are really close the front, lower, rear spring shackles and I had to clearance the left side header flange and, as a word of advice, make sure the lower shackle spring bolt is head to the inside. I'm not sure if there will be enough clearance on the passenger side yet or not since I have not ran the truck. The right header is farther back at the collector than the drivers side. I had to rework the rest of the exhaust to make everything fit back up correctly. Overall they are nice heavy headers and I don't believe they will be overall any long term issues. Not an afternoon project. The best way is to bring these headers from underneath to install. They are designed for that method unlike most cheaper headers. I hope this helps and overall I would recommend if you have some skills.

    Rated 1 out of 5 by from Do NOT FIT 88-91 This is the fourth pair of 1-3/4” headers I’ve tried. Despite JEGS “fitment” that says fits up to a 91 Like so many of their headers say. They do not fit! I should know by now that if it says it fits a square body truck it won’t fit and OBS. The headers look fine so the review is more of a heads up that Jegs web site is incorrect.

    Will these headers work with steel bowtie angle plug heads?

    Asked by: Jackie Ray
    This header is designed to fit aluminum angle plug heads only.
